The remarkable technology that permits the intake of fresh air with minimal loss to indoor temperature is know as the LOSSNAY Core. The cross-flow, plate-fin structure of the energy-recovery unit along with a specially processed diaphragm keep supply and exhaust air separate, ensuring that only fresh air is introduced to the indoor environment while also allowing for the efficient transfer of heat.

The basic principle

Relative humidity (%)
Every building needs a supply of fresh air to keep its inhabitants healthy and comfortable. Outdoor air though is rarely, if ever, , the same temperature as that maintained by the building s air conditioning system. In the summer, it is too hot. In the winter, it is too cold. This puts added stress on the air conditioner to compensate for the intake of the hot or cold air adding to the expense of operating the system. LOSSNAY all but eliminates this problem with original energy-recovery technology that uses the heat of the stale indoor air to be expelled in order to either heat or cool the incoming fresh air to a temperature much closer to the existing indoor air. This process reduces the load on the air conditioning system without cutting off the supply of vitally necessary fresh air.

The microscopically small pores of the diaphragm have been made even smaller, decreasing the rate at which water soluble gases such as ammonia and hydrogen pass through. Further, a new specially processed paper used to make the diaphragm has been developed with high moisture permeability characteristics that aid in the transference of moisture for improved energy exchange efficiency. These developments further improve moisture permeability and effectiveness in shielding unwanted gases, resulting in a lower rate of gas transference and more highly efficient energy transfer. 2
Hyper Eco Core
New function: "By-pass" Ventilation External Control Setting
Better energy conservation by improved total heat exchange efficiency.
In addition to the automatic damper open/close function, open/close control via external devices is now possible, delivering a“By-pass” ventilation system that is suitable to the installed environment.
Introducing the new Hyper Eco Element Mitsubishi's newly developed Hyper Eco Element is on board, offering the industry's best total heat exchange efficiency. Energy conservation performance has been improved not only by reducing the air conditioning load associated with ventilation, but also by facilitating humidity penetration.

1. Reduces cooling load If the air outside is cooler than the air inside the building during the cooling season (such as early morning or at night), “By-pass” ventilation will draw in the cooler outside air and reduce the cooling load on the system.
Extra Low Mode
CO2 Sensor
Additional energy conservation by using a four-level air volume system that allows more precise control.
The system allows you to measure CO2 density and thereby control the amount of fresh air supplied. By connecting a CO2 sensor to the connector CN16, which is added to the LOSSNAY main unit, the setting can be switched to High, Low, or Extra Low operation, which is selected when the sensor is turned ON. This system produces additional energy conservation.
In addition to the conventional Extra High, High, and Low modes, an Extra Low mode is added to provide a more dynamic range of air volume settings and versatility in a variety of installation environments, yielding much better energy conservation. Using a simplified timer function, it switches to Extra Low operation when the operation stop button is activated and it is accordingly possible to implement 24-hour energy conservation ventilation.

Office equipment room cooling During cold season, fresh air can be drawn in and used as is to cool rooms where the temperature has risen due to the use of office equipment. * When the outdoor air tempereture drops lower than 8ºC it changes to the heat exchange ventilation. (Display of the remote controller does not change) * In the case of “By-pass” ventilation, the supply air temperature slightly rises more than the outside air temperature because of the heat effect around the ducts or the unit motors.

Air volume level can be set hourly (max 8 times) and weekly. You can pre-set air volume according to the predictable requirement so that LOSSNAY can automatically operate at only necessary air-speed at the specified time period, which saves power consumption while maintaining the indoor air quality. Besides, once the weekly timer has been set, no switching on-off is required.

Night Purge Function
During the summer season, the Night Purge function draws cooler outside air into the room to suppress temperature rises at night. This energy conservation function reduces the load when air conditioning is started the next morning. Dot matrix display
While air conditioning and ventilation are not operating, the room temperature rises as a result of heat from the skeleton and OA equipment.
When the outside temperature becomes lower than the room temperature, ventilation starts automatically.
At night, the outside temperature drops.
Hot air is discharged.
When the room becomes sufficiently cool, ventilation is stopped.

A Breath of Freshness in Restaurants, Offices, and Schools Restaurants

A restaurant can never be too clean and its air never too fresh
Fresh air–improving the overall quality of working life
Creating the best possible environment for our children to succeed
The atmosphere of a restaurant is crucial to securing customers and making them happy enough to come back for more. Cleanliness is the key to an attractive atmosphere and restaurants devote significant effort to ensuring the premises are sanitary. Sanitation and cleanliness, however, are not enough. No matter how clean a restaurant may look, if there are bothersome odors lingering in the air, all those efforts go to waste and the restaurant's clean image is tarnished. For these reasons, we invite restaurant owners to leave the air to LOSSNAY. LOSSNAY's superior ventilation capabilities ensure that every breath is a breath of freshness keeping guests happy. LOSSNAY also keeps owners happy with its remarkable heat recovery technology that supplies fresh outdoor air with minimal change to indoor temperature, saving on energy and expense.
Many office buildings today are heavily insulated air-tight structures with little or no natural ventilation. The unnatural environment created by air conditioners without added ventilation is a breeding ground for bacteria. Factor this in with the accumulation of pollutants and odors in the form of cigarette smoke, formaldehyde, pollen, dust, and carbon dioxide, and the necessity of ventilation becomes ever more apparent. In fact, poorly ventilated buildings can give rise to Sick Building Syndrome, a malady that is known to cause headaches, sore eyes, itching, and concentration loss. This results not only in discomfort at best and sickness at worst for the building's occupants, but also the reduced productivity of the workforce. Fresh air, effectively ventilated throughout the building, is therefore essential to the overall quality of working life.
Children deserve all the help we can give for them to grow up healthy, happy, and prosperous. No matter how good a school's curriculum, no matter how positive and enthusiastic the teacher, a child who does not feel well will have a hard time learning. The constant flow of fresh air is nowhere as important as it is in our schools. In classrooms where large numbers of students are gathered for long periods of time, carbonic gases have the tendency to accumulate, decreasing the levels of oxygen that are vital for alertness and concentration. This is especially true during the winter months when windows tend to remain closed. LOSSNAY ventilates fresh outdoor air into classrooms to replenish the supply of oxygen and expels not only carbon dioxide, but also other pollutants and odors that inevitably sully the air.
If it’s LOSSNAY...
If it’s LOSSNAY...
If it’s LOSSNAY...
Ventilators work to exhaust stale air and supply fresh, clean air free of the odors associated with cooking, cigarettes, and the people working and dining.
Simultaneous forced-air supply and exhaust introduces fresh, outdoor air into the building, effectively ventilating even fully airtight structures.
The continuous influx of fresh, outdoor air and the exhaust of stale, indoor air ensure that the indoor oxygen level is maintained at just the right balance for comfort and health.
Change in room temperature is kept to a minimum during ventilation thanks to the heat-recovery function.
Multiple split-type units operate independently of one another, simplifying system set up and ensuring a layout that optimally matches nearly any office design.
Occupants have the luxury of breathing fresh air at all times even in highly air-tight buildings.
The ventilators operate very quietly so those in the midst of enjoying their meals will not be bothered by any excess noise.
LOSSNAY operation can be interlocked with air-conditioning system operation.
LOSSNAY's sound attenuation qualities prevent outside noise from penetrating into the room, helping to maintain a quiet environment for productive study.
A large array of ventilators is available to match the layout of just about any restaurant.
Heat that is commonly lost due to ventilation is collected and reused thanks to the LOSSNAY Core, reducing air conditioners’ energy load and cutting operating costs.
Heat-exchange technology prevents fluctuations in temperature for significant energy savings when either heating or cooling a room.

Attention for specifications 1.Cold operation mode(*1) is to start repeating in the case that LOSSNAY's detected OA temperature is less than-10°C. *1.Supply air(SA) in the operation for 60min. followed by stop operation for 10min. 2.The current, power consumption and efficiency are based on the air flow rate in the specification. 3.Fan speed is selectable by the remote controller from High (Extra-High), Low, Extra-Low(Extra-Low not equipped LGH150RX5 and 200RX5). Multi Ventilation Mode should set on LOSSNAY unit or remote controller (PZ-60DR-E). 4.LOSSNAY ventilation mode is to start automatically in the case that LOSSNAY's detected OA temperature is less than +8°C,even if By-pass ventilation is set by remote controller. Remote controller continue to show "By-pass ventilation" in this case. 5.Temperature Exchange efficiency(%) are based on winter condition. 6.Mitsubishi Electric measures the machine according to the Japan Industrial Standards(JIS B 8628)
Attention 1.When using the product where it is exposed to high temperatures and humidity (40°C or higher, RH 80% or higher), or where fog occurs frequently, moisture is likely to condense in the core, and may result in condensation build up in the unit.The product should not be used under such conditions. 2.Outdoor air may enter the LOSSNAY owing to the pressure difference between indoor and outdoor or external winds even when the product is not operated. It is recommended to install an Electrically operated damper to block the outdoor air. 3.In a cold weather area, an area with strong external winds or where fog occurs frequently, cold outdoor air, external winds or fog may be introduced into the product when its operation is stopped. It is recommended to install an Electrically operated damper. 4.In a cold weather area, or others, dewing or freezing could occur on the main unit, where the duct is connected, or other sections, depending on the conditions of outdoor air and indoor temperature and moisture, even if they are within the range of operating conditions. Make sure to confirm the operating conditions and other precautions, and do not use the product if dewing or freezing is anticipated. 5.The outside ducts must be tilted at a gradient (1/30 or more) down toward the outdoor louvres from LOSSNAY, and properly insulated. (The entry of rain water may cause power leakage, fire, or damege to household property) 6.The two outdoor ducts must be covered with heat-insulating material in order to prevent condensation from forming. If it is expected that the ambient temperature around the place where the LOSSNAY unit is installed will be high during the summer air conditioning season, it is recommended that the indoor ductwork be covered with insulation material. 7.Inspection opening (450 × 450 or 600 × 600mm)must be installed on the filter and LOSSNAY core removing side. 25
1.Operating environment Install this product in an environment where the temperature ranges from -10°C to +40°C and the relative humidity is less than 80%RH. If condensation is expected to form,heat up the fresh outside air should be treated. 2.Do not use under high temperature and humidity condition Condensation will occur and water will gather inside the LOSSNAY cores under high temperature and humidity condition, such as warm swimming pool, bathroom, greenhouse or foggy place. 3.Condition of outdoor, indoor and return air Avoid using LOSSNAY under air condition with acid, alkalis, organic solvent , oil mist, paint, or harmful gas as presticide, corrosive gas, etc. 4.Insulation failure caused by salt or sulphur air and hot spring steam, Rust, fire or malfunction may occur. Installing high quality filters inside outdoor air duct if the LOSSNAY operates in salt or sulphur air conditions. 5.Intake of mist or outdoor air during off-mode operation Outdoor air or mist may flow through the duct into your room when LOSSNAY is in off-mode at windy and foggy area. To prevent intake of outdoor air or fog, a damper is advised to be installed. 6.Entry of insects When using the product in an environment where there is a window,or opening near the outdoor hood,so that insects are likely to gather around the interior or exterior light,take note that small insects may intrude into the LOSSNAY filters. 7.By-pass ventilation In the case of "By-pass" ventilation, the supply air temperature slightly rises more than the outside air temperature. because of the effect around the ducts or the unit motors. 8.Usage of M-NET. When solely using LOSSNAY units, power supply unit is required to connect to centralized control. Number of power supply units or the transmission boosters should correspond with the connected LOSSNAY units.
Caution for installation 1.Do not modify the unit as it may cause malfunction. 2.Leaving sufficient space for maintenance purpose. 3.The location of the air inlet Take care in locating air inlet to prevent intake of dirty air or disgusting smell from exhaust gas of factory, air from rubbish disposal, etc. 4.Take precautions when using the product in quiet location. 5.Heat insulation foam for duct Take care as below to prevent the contaminate ceiling by duct condensation. 1)The two outdoor ducts(OA and EA) must be covered with heat-insulating material in order to prevent condensation. 2)If it is expected that the ambient temperature around the place where the LOSSNAY unit is installed will be high during the summer air conditioning season, it is recommended that the indoor ductwork be covered with insulation material. 3)Outdoor air may come into unit during not operating unit by the pressure difference between indoor and outdoor or the outdoor wind. In this case you should install a damper. 4)It is possible for condensation and freezing to occur in the cold regions inside the unit because of the outdoor air condition or humidity condition above ceiling. Make sure to install supplemental insulation foam. 5)In the case that air condition around LOSSNAY unit is high temperature in summer, it is recommended that there are heat insulation foam on indoor side duct to prevent heat recovery decreased by warming indoor duct. In winter, it is possible to cool indoor side duct without heat insulation foam on indoor side duct. 6.Prevent entry of rainwater into LOSSNAY unit Install weather louvre or "Weather cover" for OA inlet & EA outlet. This is to prevent rainwater entering the LOSSNAY unit. Ducts to outdoor (OA and EA) should decline by 1/30 or more. 1)Install the anchor bolts to ensure the product's weight or earthquake load. (Correctly rated wire/chain may also be used) 2)Do not install this product in a place where it is exposed to ultraviolet light. (UV may be damage covering insulation.) 7.Electrical Work A single pole isolator must be installed at the origins of mains power supply. Use single flush box, to support remote controller. Must connect ground wiring. When connecting external devices (electrically operated damper, lamp, monitoring unit, etc.) using output signals of the LOSSNAY unit, make sure to install safety equipment for the external devices. (It could cause fire, damage, etc. without safety equipment)
